T 0 all whom it may concern. Y

Be it known that I, Josii GONZALEZ BABIO, a citizen of the United States, residing at New York city, borough of Manhattan, and county and State of New York, have invented certain Improvements in Window-Cleaning Chairs, of which the following is a specification.

The invention relates to that class of chairs known as window cleaning chairs, and the purpose of the invention is to provide a chair of this type that will be simple, as light as possible, consistent with strength, and which in addition tobeing economic in manufacture, will be absolutely safe and convenient to the operator under all conditions of use.

It is a further purpose of the invention to provide a chair of the character described that can be readily adapted to any window sill or frame, and in which a person can be safely seated, occupying such positionthat windows can be cleaned inside or out, the top sash being as readily accessible as the bottom one.

It is also a purpose of the invention to so derstood that the details of constructionmay be varied without departing from the spirit of the invention.

In the drawings-Figure 1 is a rear elevation of the chair applied to a window frame; Fig. 2 is a section through the window frame, and a plan view of the chair with the seat removed; Fig.3 is a detailver--- tical section through the chair, the section being taken on the line 3, 3, of Fig. 1 Figs. 4 and 5 are detail views of different means for locking the chair in place, and Fig. 6 is a transverse section of an adjustable leg support for the chair.

As has been stated, the chair is adapted to. any type of window frame A, and in con-, nection with a window frame, I employ stationary fixtures of a simple construction whereby to readily and expeditiously attach the improved chair and remove it fromlockmg engagement with the wlndow frame or w vices a, sho'wn'm Fig. 4 which devices are sill A.

In FigsJt and 5,"I have shown two forms of such devices designated, respectively as a and=b. The device 0., shown in Fig. 4, is in the nature of a hook having a screw shank 10, and afla'nge 11, at the junction of the hookbody with the shank. This fiangemay be apertured to receive wood screws and theshank .may be in the form of a spike, and when the shank is threaded, the screw holes may be omitted from the said flange. desired number of said retaining fixtures may be employed and are properly distributed at the inner faceof the window sill A, as is shown in Figs. 2 and 3. The hook-like devices a'are adapted to be secured upon the inner surface of the window casing below the window sill, as clearly shown in Fig. 3.

With reference to the fixture I), 111118? trated in Fig. 5, it is in the form of a socket platedhaving a curved diagonal or circuitous slot 12, produced therein. Suitable members are provided for the seat frame B, of the chair, as willbe hereinafter described, fitted.

to the fixture, shown in Fig. 4, or that shown in Fig. 5; As herein shown, the frame 13 of I and afront bar 16, either removable from or integral with the sides of the body portion of the frame. I

The seat proper 17 which may be a board As illustrated, the angle iron forma-.

or its equivalent rests upon the back section v 13, of the, frame and the forward crossbar I 16, as 1s shown in Flg. 3, but other means.

maybe employed for its support, and any desired number of transverse brace bars may be employed in the construction of the seat frame, as is illustrated 'at 18, in Fig.2. As

herein shown the forward end portions of the seat frame B, and also when desired its forward central portion, downwardly extending latch members 19, are provided which may be either integral with or attached to said frame and each latch member.

19,-is provided with an eye 20, that receives a hook body of the type .of fastening depractically keepers. The hook-like members a have downwardly directed bills which are adapted for locking engagement with the eyes 20, when the seat portion is supported upon the window sill, shown in Fig. 3. When, however, the form of fastening device 6 is employed, shown in Flg. 5, downwardly extending members 19 are used instead of the members 19, and the said members 19*, instead of terminating in eyes 20, terminate in curved or angular tongues 20, that enter the slots 12, in the said keepers or fastening devices I). In this manner the forward portion of the chair may be quickly and securely attached to the inner portion of any window sill.

With reference to the means of support for the outer or back portion of the chair, said supporting means is capable of adjustment to and from the forward or inner portion of the chair, so as to accommodate the said supporting means for efiective engagement with window sills of varying width. This supporting means in the form illustrated in Figs. 1, 2 and 3, consists of a bot tom bar 21, having upwardly extending side members 22. As shown in these views, the bottom of the frame B, rests upon the bar 21, and the sides of the frame are received between the side members or flanges 22, of the bar. In this way, the weight of the frame B and its occupant will serve to hold the support in adjusted position; but if de sired, provision may be made for holding the bar 21 and its flanges 22 fixedly to the frame of the chair. In the structure herein shown the flanges 22 of the supporting member 21 are provided with vertically directed bearings 23, 23 wherein are held for vertical sliding movement the vertically directed upper parts or shanks of L-shaped legs or supporting members 24, 24, one of which is provided at each side of the chair, the lower ends of said legs being arranged to project beneath the frame and having their extremities provided with laterally directed extensions or feet 25, 25 which are integral with and project substantially at right angles from the vertically directed parts or shanks of said legs or member 24, and have their undersides adapted to fit flush on the top surface of the window sill in such a way as to afford effective support for the outer part of the chair during use. The shanks of said legs 24 are capable of both rotatory and vertical sliding movement in the bearings 23, and said bearings have set screws 26 engageable with the shanks for holding the legs in adjusted position. By this construction of the parts it will be seen that when the screws 26 are loosened, the legs 24 may be adjusted to vary the extent to which their laterally directed feet or extensions 25 proect beneath the frame, so as to accommodate difierent elevations of the window sill,

the shanks of said legs 24 playing freely endwise in the bearings 23 during such adjustment, and by rotating said legs their laterally directed feed or extensions 25 may be caused to project either inwardly or outwardly from their upper or shank portions, so as to accommodate the device to window sills of different widths without requiring adjustment of the legs horizontally upon the frame of the device, the shank portions of the legs or members 24 turning freely within the bearings 23 during such rotation of said legs or members.

In Fig. 6, I have illustrated a slight modification in the formation of the rear adj ustable support for the seat frame, wherein a cross bar 27, is employed that slides beneath the frame, and said cross bar has upwardly extending members 28, at its ends of sufiicient dimensions to constitute bearings, and each bearing has a vertical opening 30, to loosely receive the shank of a leg 24, and an opening 31, for the passage of a set screw to the shank of a leg. The flange extensions or bearing members 28 are extended up outside of the outer opposite surfaces of the side members 14 of the seat frame and are each provided with an inwardly extending guide member 29, which members are capable of sliding movement upon the upper faces of the side members 14, of the seat frame B, and said guide members 25), are provided with apertures 32, for the reception of set screws whereby to hold the support in adjusted position relatively to the seat frame B. As a further means for holding the said frame support in adjustment, screws 33, are passed up through the cross bar 27, being adapted to enter the seat. It may here be remarked that the seat may be secured to the frame B in any approved manner, and that the seat may be made of any suitable material, and that the seat frame may be provided with one or more handles 34.

As herein shown, the improved chair is provided with a back 35 of such shape and dimensions as to be adapted to conceal the occupant of the chair from passers-by. If desired, this back may be rigidly attached to the frame B or other part, or as herein illustrated may be hinged thereto so as to fold down over the seat portion of the chair when the device is not in use, so as to oecupy as small a space aspossible. To accomplish such pivotal or foldable connection of the back with the seat portion of the chair, said back 35 is provided at its opposite sides with integral forwardly directed portions 35, 35 which are pivoted at 36 upon alined lugs 37, produced at opposite sides of the frame B of said seat portion of the chair, the points of pivotal connection of said forwardly directed portions 35 with the seat portion being closely adjacent to the upper surface of the seat frame B, so that said back may be folded closely adjacent. to the seat portion in order that the device may occupy comparatively small space whennot required for use. I 1

The forwardly directed portions'35 35 at the opposite sides of the back 35 of the improved chair have forward hedge surfaces 35*, 35 which are adapted, when the back of the chair is in folded condition, to contact upon the top, surface of the seat frame B along the opposite sides thereof in' such a manner as to effectively retain the back 35 slightly elevated from the upper surface of the seat portion of the chair, whereby a space or chamber is produced between the seat portion and back 35 when the chair is in folded condition, in which space or cham-' ber cleaning rags or the like may be con veniently retained and carried about from window to window.

The formation of the forwardly directed port-ions 35, at opposite sides of the chair back with the forward edge surfaces 35, adapted to fit flush upon the top surface of the seat frame as above set forth, efiectively closes the sides of the space or chamber between said back and seat portion of the chair when" the device is compact-ed, and said edge surfaces 35 are rearwardly inclined from their lower parts toward the top of the chair back 35, so that when the back is folded down, closely adjacent tothe seat portion of the chair, the upper'edge of said back 35, which then occupies a position adjacent to the forward edge of the seat portion, is caused to approach much closer to said seat portion than its lower edge portion, whereby it will be seen that the space or chamber formed between the parts as above described, is substantially closed by such close approach of the top edge of the back toward the seat portion along the forward edge of the latter, thereby effectively guarding against the falling of the cloths or other articles from said space or chamber when the device is carried from place to place. The formation and arrangement of the parts are also such that the lower edge of the back 35, at points between the forwardly directed lateral portions 35*, 35 is adapted to fit accurately upon the top surface of the frame member 13 when the back of the chair is raised, so that said forwardly directed sides or lateral portions 35, 35 being pivotally connected with the seat frame at points in advance of the point of contact of said lower edge of the back upon the seat frame, afford braces which operate effectively for strengthening and bracing the chair back when the same is elevated during use of the improved chair. a

It is obvious that the chair in its'entirety is very simple and that it may be made light and strong and can also be convenlently and expeditiously placed inposition on a window $111 or removed therefrom.

What I claim'as new and desire to secure by Letters Patent is 1.,A window cleaning chair having a frame, supporting means comprising an L- shaped member having a vertically directed shank mounted for turning and endwise sliding movement upon the frame, and provided at its lower extremity with a laterally directed part integral with said verti-' cally directed shank, and engageable with a window sill and adapted to be moved across the surface of such sill when the shank is turned upon the frame, and means for locking said L-shaped member to the frame.

.2. A window cleaning chair having a frame provided with bearings, L-shaped members each having a vertically directed shank mounted for turning and endwise sliding movement in one of the bearings of the frame, and each provided at its lower extremity with a laterally directed part integral with said vertically directed shank and engageable with a window sill, and adapted to traverse the surface thereof during turning movement of said shank, and set screws or'locking said members against movement in said bearings of the frame.

' A window cleaning chair having a frame provided with means for holding it to a window frame, and having a seat portion, and a back having forwardly directed rigid side portions at its opposite sides and pivotally connected with the frame adjacent to the upper surface of its seat portion and in front of the rear edge thereof, said back when moved in one direction upon the pivotal connections of its side portions with the frame being adapted to stand vertically above said frame with its lower edge engaged and supported upon the rear part of ,said'frame and being adapted, when re- 'verselymoved upon the pivotal connections of its side portions with said frame, "to be folded down adjacent to the seat portion but spaced apart therefrom to produce a chamber between said back and the seat por- -tion, the said forwardly directed side portions having edge surfaces adapted, when the back is thus folded, to closely approach the seat portion and close the sides of said chamber.

4. VA window cleaning chair having a frame provided with, seat portion, and a back having forwardly directed side portions integrally produced at its opposite sides and pivotally connected with the frame adjacent-to the upper surface of its seat portion and in front of the rear edge thereof,

said back when moved in one direction upon therpivotal connections of its side portlons with the frame being adapted to stand vertically above said frame with its lower edge engaged and supported upon the rear part of the frame, and being adapted, when reversely moved upon said pivotal connections, to be folded down adjacent to the seat portion, but spaced apart therefrom to produce a chamber between said back and the seat portion, the said forwardly directed side portions of the back having edge surfaces inclined from the pivotal connections of the side portions toward the upper edge of the back and adapted, when the back is folded, to closely approach the seat portion and close the sides of said chamber, the inclinations of such edge surfaces being also adapted to permit the upper edge of the back, when folded, to approach the seat portion more closely than the lower edge of the back and thereby close said chamber along the forward edge of the seat portion.

In witness whereof I have hereunto signed my name this 26th day of September 1908, in the presence of two subscribing witnesses.
